BlueBear, I am very happy with both the front and rear Rizoma axel protectors. The pictures do not really give them justice and as such I would recommend you check them out from one of your dealers. The Rizoma rear axel protector is pricey, however it is a real work of art. It comes with a custom tool for quick installation and removal of the rear hub protector. When the rear or front axel protector is fitted you can not use the relevant stands.
With regards to the exhaust the Tech Mechanics are pretty skilled and they charged me for 3 hours total time, to pull a full Termi' off the bike, strip it down, re-assemble it and put it back on the bike. You can get rates from Jet Hot or in your case a local dealer as this all depends on what work and how fast you require it to be completed.
